Non-targeted screening strategies for identifying per- and polyfluoroalkyl substances (PFAS) in complex food matrices present significant challenges. PFAS are a group of human-made chemicals that are resistant to degradation and can accumulate in the environment and living organisms. The complexity of food matrices, which can include various components like fats, proteins, and carbohydrates, complicates the detection and quantification of PFAS.
Current analytical methods often rely on targeted approaches that may overlook unknown PFAS compounds. Non-targeted screening, while promising, requires advanced techniques such as high-resolution mass spectrometry to effectively identify a wider range of PFAS. However, the variability in food composition and the presence of numerous interfering substances can lead to difficulties in interpretation and quantification.
Moreover, regulatory frameworks for PFAS detection in food are still evolving, creating additional challenges for researchers and food safety authorities. As the understanding of PFAS toxicity and prevalence grows, developing robust non-targeted screening methods becomes increasingly crucial to ensure food safety and protect public health.
